Harvey, 19, was the Orioles' first-round pick in last year's first-year player draft. The son of former All-Star closer Bryan Harvey, he was 0-1 with a 1.78 ERA in eight starts between the rookie-level Gulf Coast League Orioles and short-season Single-A Aberdeen in 2013.

Rodriguez, 20, split the 2013 season between high Single-A Frederick and Double-A Bowie. He was 10-7 with a 3.41 ERA in 25 starts between the two levels.

Schoop, 22, also made his major league debut last season. He batted .286 (4-for-14) with a solo home run and five runs scored in five games for the Orioles in September. He hit .256 with nine home runs and 34 RBIs in 70 games for Triple-A Norfolk in 2013.

Orioles executive vice president Dan Duquette has trumpeted his philosophy that the franchise's long-term success will hinge on its ability to develop its own pitching rather than spend money on big-ticket free-agent pitchers.
